An application that shows you if your train will be late, and that in real-time! Even better, imagine that bundled with an API that gives you access to all that data. So happened in Germany with the application Zugmonitor (German for train monitor) and the corresponding Zugmonitor API.

WestJet, a low-cost Canadian airline, has announced that iTravel2000 intends to integrate the WestJet Direct API to book and ticket air travel. In addition to the API integration, iTravel2000 will become a WestJet-certified conforming channel early next year. The certification will permit iTravel2000 to continue access to WestJet's best possible prices and ancillary products.
